Sydney, Australia — June 2, 2025 — Two Australian companies at the forefront of hydrogen-powered aviation have successfully registered a family of liquid hydrogen tanks that will pave the way for zero-emission flights across the country. This milestone marks a significant step forward in the development of sustainable aviation technology.
AMSL Aero and Stralis Aircraft have partnered with BOC Australia to register the tanks, known as “Dewar vessels,” which will be used to store and transport liquid hydrogen to fuel aircraft. These tanks work similarly to large-scale thermos flasks, maintaining a vacuum to insulate the super-cold liquid hydrogen required for the next generation of eco-friendly aircraft.
The registration of these Dewar vessels, the first of their kind to arrive in Australia, is crucial for the future of hydrogen-powered aviation. With a capacity of 30 kg per vessel, they will be used to transport liquid hydrogen from production plants directly to aircraft for refuelling, enabling zero-emission flights.
Revolutionizing the Aviation Industry
“There is now a strong global consensus about liquid hydrogen as an aviation fuel. AMSL Aero is delighted to help build another link in a liquid hydrogen supply chain for Australian aviation alongside BOC and Stralis.” – Simon Coburn, Hydrogen Systems Engineer at AMSL Aero
The collaboration signals a new chapter in Australia’s ambitions to lead in sustainable aviation technology. AMSL Aero’s flagship aircraft, the Vertiia, which is currently in development, is set to become one of the first zero-emission aircraft to benefit from this advancement. The Vertiia is a hydrogen-electric VTOL aircraft designed to revolutionize regional air travel with minimal environmental impact.
A Critical Step for Australia’s Hydrogen-Electric Future
For Stralis Aircraft, a leader in hydrogen-electric aircraft design, this step is essential in making zero-emission aviation a reality.
“This is a key step forward for hydrogen-electric aircraft in Australia, enabling liquid hydrogen refuelling for ground and flying demonstrator aircraft, and supporting the development of a liquid hydrogen supply chain in Australia for future commercial flights.” – Stuart Johnstone, CTO and co-founder of Stralis Aircraft
The successful registration of these Dewar vessels ensures that the country is on track to create the infrastructure needed to support the widespread use of hydrogen in aviation, with the potential to transform the sector on a global scale.
BOC’s Commitment to Clean Energy Innovation
“BOC has a long history of working with hydrogen in Australia. It’s always exciting to see innovation and new applications emerge, and we’re pleased to be able to support efforts like these to unlock new opportunities.” – Chris Dolman, Business Development Manager for Clean Energy at BOC South Pacific
BOC, part of the global Linde Group, has been at the forefront of the hydrogen industry in Australia, and this collaboration is another example of its commitment to supporting clean energy technologies. Founded in 1886 BOC as Brin’s Oxygen Company Ltd (which was later changed to British Oxygen Company Ltd in 1906), BOC started operations in Australia in 1935 as Commonwealth Industrial Gases (CIG).
Looking Ahead
As hydrogen-powered aircraft continue to develop, the successful registration of these liquid hydrogen tanks will be key to supporting the next phase of flight tests and demonstrations. With a global push for greener aviation technologies, this breakthrough brings Australia closer to its goal of reducing aviation’s carbon footprint and creating a future where sustainable air travel becomes the norm.
In the coming months, AMSL Aero and Stralis Aircraft are expected to continue advancing their hydrogen-powered aircraft, while BOC will help ensure the hydrogen supply chain is robust enough to meet the demands of the industry.
This is just the beginning of a journey that could forever change the landscape of aviation, both in Australia and across the globe.
